_This Diversity accounted for._--To which I reply, the thing has been already accounted for. Our ideas of right and wrong, it was stated, in discussing their origin, depend on circumstances for their time and degree of development. They are not irrespective of opportunity. Education, habits, laws, customs, while they do not originate, still have much to do with the development and modification of these ideas. They may be by these influences aided or retarded in their growth, or even quite misdirected, just as a tree may, by unfavorable influences, be hindered and thwarted in its growth, be made to turn and twist, and put forth abnormal and monstrous developments. Yet nature works there, nevertheless, and in spite of all such obstacles, and unfavorable circumstances, seeks to put forth, according to her laws, her perfect and finished work. All that we contend is, that nature, under favorable circumstances, develops in the human mind, the idea of moral distinctions, while, at the same time, _men may differ much in their estimate of what is right, and what is wrong_, according to the circumstances and influences right and wrong to particular cases, and decide as to the morality of given actions, is an office of judgment, and the judgment may err in this, as in any other of its operations. It may be biassed by unfavorable influences, by wrong education, wrong habits, and the like. _Analogy of other Faculties._--The same is true, substantially, of all other natural faculties and their operations. They depend on circumstances for the degree of their development, and the mode of their action. Hence they are liable to great diversity and frequent error. Perception misleads us as to sensible objects, not seldom; even in their mathematical reasonings, men do not always agree. There is the greatest possible diversity among men, as to the retentiveness of the memory, and as to the extent and power of the reasoning faculties. The savage that thinks it no wrong to scalp his enemy, or even to roast and eat him, is utterly unable to count twenty upon his fingers; while the philosopher, who recognizes the duty of loving his neighbor as himself, calculates, with precision, the motions of the heavenly bodies, and predicts their place in the heaven, for ages to come. Shall we conclude, because of this diversity, that these several faculties are not parts of our nature?
